Structural and visible lumber
Wood selection needs to distinguish the supporting frame from the visible walking boards and trim. Species, grade, treatment and use conditions help define the appropriate material for each component. A pressure-treated label alone does not describe every application. Coordinate the actual lumber with the structural design and compatible hardware. The finished deck can have a consistent appearance without assuming that posts, joists, boards and fascia all use an identical specification or that decorative wood is suitable for every support.
